Questions & Answers about Tarvitsemme raketin moottoriin kehittyneemmän komponentin.
How do we get the comparative form kehittyneemmän from the base verb kehittyä?
First, we form the past active participle kehittynyt (advanced or developed). To make it comparative, the -nyt ending changes to its stem -nee-, followed by the comparative marker -mpä-. Because this sentence requires the accusative case ending -n (which closes the syllable), the -mpä- undergoes consonant gradation and weakens to -mmä-, resulting in kehittyneemmän.
Could we use the participle of the verb kehittää instead of kehittyä here?
No, because kehittää is transitive (to develop something). Its past participle kehittänyt describes someone or something that has developed something else. We want to describe a component that is advanced in itself, so we must use the intransitive verb kehittyä (to evolve or develop), which yields kehittynyt.
Why is the object kehittyneemmän komponentin in what looks like the genitive case?
It is actually the accusative case, which shares the -n ending with the genitive for singular nouns. The verb tarvita (to need) takes this total object because we need one whole, specific component, and the sentence is a standard affirmative statement.
Why is 'for the engine' translated with the illative case moottoriin (into the engine) instead of the allative moottorille?
When talking about parts, accessories, or components that belong to or are installed in a larger machine, vehicle, or system, Finnish typically uses the illative case. You are conceptually installing the component into the engine.
